Description
本发明涉及钻井工程技术领域,特别是涉及一种钻井液混合清洁搅拌装置及其控制方法。
钻井液的混合搅拌是固控系统中不可缺少的工艺。混合搅拌主要是为了防止钻井液沉淀,钻井液密度偏小(偏大)时对钻井液进行加重(稀释)作业后对钻井液进行搅拌,使罐内钻井液密度基本恒定。一般的搅拌叶轮只有搅拌作用,不能对罐底沉砂进行充分搅拌混合,以致搅拌效果不理想;此外,现有技术中的罐体一般为长方体,角落里的钻井液长期不能被搅拌混合,始终不能参与整个钻井液的循环作业,时间一长就会逐渐沉淀,对钻完后清砂带来很大的困难。
罐体沉砂的清除也是非常棘手的问题,打完井后,都需要人工进行清砂,虽然泥浆枪有清洁作用,但是其效果实在太小基本起不到清洁的作用,所以现有钻井队几乎没有用泥浆枪进行清砂作业的,都是人工进行清砂。由于钻井液沉淀后非常坚硬,有的时候需要用钢钎进行清除,所以员工的劳动强度非常大。
申请号为CN201720166926.7的实用新型专利公开了一款喷头叶轮,这款喷头叶轮基本解决了上述问题,但工艺麻烦,且喷头数量有限,这款喷头叶轮沿用以往的叶轮样式,叶片通过安装板与输液管连接,安装板上下的液体得不到搅动,叶轮输送能力加强有限,由于喷头直接组焊在输液管上,如果叶轮转速快,喷头喷出水后由于转速太快水柱不能成行,如果转速慢,对液体的搅动效果又不好,这一点此喷头叶轮没有解决。
申请号为CN201720226751.4的实用新型专利公开了一种钻井液混拌清洁装 置,其工况为搅拌时液体呈现漩涡状液体流,混合时液体呈现喷泉状液体流,液体的流动方向和液体喷出的方向相同,液体的冲击力阻止了叶轮的旋转,叶轮需要更大的转矩才能实现工作,电机的输出功率较大。
另外,在钻井时,需要使用到一些混配的钻井液以辅助钻井。钻井液中的各种成分均匀混合,能使钻井液更好地发挥效果。现有的搅拌装置往往是通过动力传动轴直接与电机转轴连接,动力传动结构功能十分单一。混合液体输入搅拌装置进行搅拌,是通过在搅拌罐上设置专门的液体进口,直接将各种液体注入搅拌罐中。直接将液体注入搅拌装置搅拌时,液体没有经过初步的混合,在搅拌过程中,液体混合不均匀会导致后续的混合液混合不均匀,混合效果不佳。
申请号为ZL201720186632.0的实用新型专利中公开的钻井液混配装置基本解决了上述问题,但是由于进液端中心线和传动中心线相交,进液效果不好,且内旋转体的进液孔中心线和内旋转体中心线相交,内旋转体有一定厚度,内旋转体在旋转时,钻孔的壁厚会阻挡液体的进入,并且也不能对钻井液中大颗粒起到一个剪切作用。
发明内容

为实现上述目的,本发明采用的技术方案是:

优选的,所述外旋转体的顶部和底部分别设有上钢球槽座和下钢球槽座,所述上钢球槽座的内侧壁和下钢球槽座的内侧壁上均开设有钢球槽,且位于上钢球槽座上的所述钢球槽延伸至上钢球槽座的顶面,位于下钢球槽座上的钢球槽延伸至下钢球槽座的底面,所述钢球槽内安装有钢球,所述内旋转体和外旋转体通过所述钢球转动连接,所述上钢球槽座上端设有上钢球槽压盖,所述上钢球槽压盖与上钢球槽座通过螺栓连接,所述上钢球槽压盖上端可拆卸的扣合有第一安装座,所述下钢球槽座的下端设有下钢球槽压盖,所述下钢球槽压盖与下钢球槽座通过螺栓连接。

通过设置喷缝,改变了以往设置喷嘴的方式,能更好地达到清理沉砂的效果,另外,设置的喷嘴容易陷入罐体底部的沉砂中,使得叶轮转动所需扭矩增大,造成能源浪费,而设置的喷缝是在第一进液轴管上直接开设条孔,因此不需要增加扭矩便能轻易实现该钻井液缝喷叶轮的运转;通过设置喷缝的出液方向与第一进液轴管在喷缝位置处的切线方向形成锐角,这样便保证了喷缝在出液时在水平面上有一定的倾角,当该装置进行搅拌工作时,先启动喷缝喷液,喷缝喷液形成一定的反作用力,辅助驱动第一进液轴管往相反方向转动,提升了该装置搅拌功能的启动效率,此时喷缝喷出液体的方向和叶轮叶片倾斜的方向相同,叶轮叶片的下面为工作面,叶轮叶片将液体压向罐底,使钻井液形成漩涡状液体流,减小了叶轮的转矩;当该装置实施混合功能时,此时喷缝喷出液体的方向和叶轮叶片倾斜的方向相同,叶轮叶片的下面为工作面,叶轮叶片将液体压向罐底,使钻井液形成漩涡状液体流,减小了叶轮的转矩;当该装置实施清洁功能时,此时罐中无钻井液,开启混合传动装置阀门并启动第一进液 轴管,此时喷缝喷出的液体形成一个覆盖面,增大了对罐底的清洁面积,大大提升了清洁效果,此时叶轮旋转方向与喷缝喷出液体方向一致,进一步加强了喷缝喷出液体的冲击力,这样使得罐底的沉积得到最大限度的清洁,本专利中的喷缝叶轮的喷缝喷出的液体和叶轮的倾斜方向相同,其工况为,搅拌功能时液体呈现漩涡状液体流,混合时液体呈现漩涡状液体流,清洁时液体呈现喷泉状液体流,这样的设计可以减小叶轮的转矩,从而可以减小电机的功率节省能源;通过设置内层孔的上边缘高于外层孔的上边缘,内层孔的下边缘高于外层孔的下边缘,这样便使得喷缝处形成了一个向下的倾斜面,这样便能够增强喷缝向下的冲击力,更进一步提升了清理沉砂的效率。
优选的,所述叶轮包括一端固定在所述第一进液轴管外壁上的叶片,所述叶片的自由端连接有叶片围板,所述叶片围板为方形结构。

本发明还提供了一种钻井液混合清洁搅拌装置的控制方法,其技术方案是:
一种钻井液混合清洁搅拌装置的控制方法,包括搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法。
优选的,所述搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法为全自动的控制方法,其中:
搅拌功能的控制方法具体包括以下步骤:操作者按下搅拌按钮,系统开启混合传动装置阀门,待阀门完全开启后系统自动启动电机,此时电机带动叶轮做逆时针旋转,叶片下叶面为工作面,液体呈现旋涡状液体流,待叶轮旋转稳定后,系统关闭混合传送装置的阀门,此时处于搅拌状态,搅拌完成,操作者按下停止按钮,系统关闭电机,完成搅拌功能。
搅拌功能:在需要对钻井液进行搅拌时,为了减小叶轮的轴向受力设计叶轮的旋转后的液流方向为漩涡状液体流,由于喷缝喷出液体的方向与叶轮的倾斜方向相同,液体喷出后的反作用力使叶轮叶片的下面为工作面,而电机旋转时带动叶轮旋转时,也是设计成叶轮叶片的下面为工作面,喷缝喷出的液体不 仅冲散了叶轮下部周围钻井液使其呈现悬浮状态,而且喷缝喷出的液体给叶轮一个旋转的力从而减小了电机启动的转矩,辅助电机的旋转。搅拌功能的运行程序为:首先混合传动装置阀门打开,钻井液进入叶轮轴管并从轴管的喷缝喷出,由于喷缝喷出的方向和叶轮叶片倾斜的方向相同,液体喷出的钻井液使叶轮下端的钻井液被冲散,并使其处于悬浮状态,在喷出液体的反作用力下使叶轮叶片下面为工作面,然后启动电机带动叶轮旋转,电机带动叶轮旋转把液体压向罐底,使钻井液形成漩涡状液体流,而喷缝喷出的钻井液与漩涡状液体流的钻井液方向相同,加速了钻井液的流动并给叶轮一个转动力辅助叶轮旋转,待叶轮旋转平稳后,关闭混合传动装置阀门,该装置一直处于此运行状态,直到人工关闭搅拌功能为止。
混合功能的控制方法具体包括以下步骤:操作者按下混合按钮,系统开启混合传动装置阀门,待阀门完全开启后系统自动启动电机,此时电机带动叶轮做逆时针旋转,叶片下叶片为工作面,液体呈现旋涡状液体流,此时处于混合状态,混合完毕,操作者按下停止按钮,系统关闭混合传动装置阀门以及电机,完成混合功能。
混合功能:混合功能是辅助加重系统对钻井液进行加重(稀释)作业,为了减小叶轮的轴向力以及叶轮的转矩选择液体流为漩涡状液体流。当在加重时,将混合传动装置的阀门和加重系统的输出管线直接连通,加重作业时先打开混合传动装置阀门,加重系统输出管线运输来的钻井液进入叶轮轴管并从轴管的喷缝喷出,由于喷缝喷出的方向和叶轮叶片倾斜的方向相同,在喷出液体的反作用力下使叶轮叶片下面为工作面,然后启动电机带动叶轮旋转,电机带动叶轮旋转把液体压向罐底,使罐内液体形成漩涡状液体流,而喷缝喷出的液体与漩涡状液体流的钻井液方向相同,加速了罐内液体的流动并给叶轮一个转动力 辅助叶轮旋转,加速了液体的流动,加快了液体的混合,直到加重作业完成,当混合完成后,只需要关闭混合传动装置的阀门就可以了,此时叶轮仍然处于搅拌状态,直到停止运行关闭电机。
清洁功能的控制方法具体包括以下步骤:操作者按下清洁按钮,系统自动开启电机,电机带动叶轮顺时针旋转,待叶轮旋转平稳后,系统开启混合传动装置阀门,此时处于清洁功能状态,清洁完毕,操作者按下停止按钮,系统关闭混合传动装置阀门以及电机,完成清洁功能。
清洁功能:清洁功能为最后清洁罐体用。此时罐体内的钻井液已经基本放完,罐内只剩下罐底的沉砂,叶轮基本处于悬浮状态。为了加大液体的喷射冲击效果,叶轮的旋转与喷缝喷出液体的方向相同,也就是说如果此时罐内有液体的话,叶轮叶片的上面为工作面,叶轮旋转时使液体呈现喷泉状体液流。当需要对罐底进行清洁时,首先把清水管线和泥浆枪管线或加重输出管线连接,启动电机,电机带动叶轮旋转,待叶轮旋转平稳后,混合传动装置阀门开启清水进入,清水不仅可以用来冲击罐内的沉砂,清水在泥浆枪管线或加重输出管线内流动时也对泥浆枪管线内的沉砂和加重输出管线内的沉砂进行了清洁,清水从喷缝内喷出,由于液体喷出的方向和叶轮旋转的方向相同,叶轮旋转加强了喷缝喷出液柱的冲击效果,从而更有效的冲击罐底的沉砂,沉砂被不停地冲击,并被水流带走,从而有效的清洁了罐底的沉砂。
以上搅拌功能、混合功能、清洁功能之间可以相互切换。如在搅拌功能状态下开启混合功能,操作者只需要按下混合按钮即可,系统会按照相应程序切换到混合功能。
优选的,所述搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法为半自动的控制方法,具体包括以下步骤:
搅拌功能、混合功能、清洁功能无非就是控制电机的正反转以及与混合传动装置阀门的配合问题,把电机的正反转控制以及混合传动装置的阀门的开关控制分开,将搅拌混合设置为一个按钮,控制电机的反转,清洁设置为一个按钮,控制电机的正转,然后阀门的开关设置为两档三位旋钮,控制阀门的开关,通过人机的组合来实现搅拌、混合、清洁功能。
优选的,还包括手动旋转叶轮的功能,具体包括以下步骤:在电机尾部或者变速箱的另外一边设置一个手动盘,通过手动盘带动电机尾部或变速箱蜗杆旋转,进而带动叶轮进行旋转。
本发明的有益效果是:
1、本发明在内旋转体正转和反转时都有利于液体的进入,并对液体进行一个初步的剪切作用,进液效果好,混合效果好。
2、当内旋转体和外旋转体出现卡死的情况时,可以把固定螺栓拆除,利用螺孔把外旋转体与上端盖或外旋转体与下端盖分离开来,从而把钢球从钢球槽内直接取出,有效的解决了钢球卡死后无法取出造成整个混合传动装置报废的问题。
3、本发明通过在进液轴管上开设喷缝,改变了以往设置喷嘴的方式,能更好地达到清理沉砂的效果,另外,设置的喷嘴容易陷入罐体底部的沉砂中,使得叶轮转动所需扭矩增大,造成能源浪费,而设置的喷缝是在进液轴管上直接开设条孔,因此不需要增加扭矩便能轻易实现该钻井液缝喷叶轮的运转。
4、本发明对钻井液的搅拌效果,实现了罐体内沉砂的自动化清除,增强清砂效果,减少人力成本的投入,同时,减小了混合时叶轮的转矩,从而减小了电机的功率节省能源。
5、本发明将主叶片和副叶片设置为“J”型或者“S”型,这样进一步增强 了叶片的强度,提升了该装置整体运行的稳定性。

在外旋转体10的顶部和底部分别设置上钢球槽座16和下钢球槽座17,上钢球槽座16和下钢球槽座17上的钢球槽18分别延伸至上钢球槽座16的顶面和下钢球槽座17的底面,在上钢球槽座16和下钢球槽座17上分别设置上钢球槽压盖20和下钢球槽压盖22,并通过螺栓固定,当内旋转体9和外旋转体10出现卡死的情况时,可以把固定螺栓拆除,将上钢球槽座16与上钢球槽压盖20或下钢球槽座17与下钢球槽压盖22分离开来,将钢球19暴露出来,可以方便把钢球19从钢球槽18内直接取出,有效的解决了钢球19卡死后无法取出造成整个混合传动装置4报废的问题。
在外旋转体10的外侧壁上设有与钢球槽18连通的油管23,可以将润滑油注入到钢球槽18内,对钢球槽18内的钢球19进行润滑,方便内旋转体9和外旋转体10之间的相对转动。

实施例3
如图8所示,本实施例在实施例1的基础上,搅拌杆5包括第一进液轴管31,第一进液轴管31上安装有八组叶轮,第一进液轴管31的管壁上均匀开设有多个喷缝38,喷缝38的出液方向与第一进液轴管31的轴向之间的夹角为锐角,叶轮包括一端固定在第一进液轴管31外壁上的叶片32,叶片32的自由端连接有叶片围板33,叶片围板33为方形结构。
八组叶片32对称分布于第一进液轴管31的外壁上,且叶片32呈“J”型或者“S”型设置。
叶片32的自由端边缘增设叶片围板33,在叶轮运转的过程中,叶片围板33可以增强对钻井液向上或者向下的输送能力,增强了搅拌过程中的混合能力;同时,将叶片32设置为“J”型或者“S”型,这样进一步增强了叶片32的强度,提升了该装置整体运行的稳定性。
通过设置喷缝38,改变了以往设置喷嘴的方式,能更好地达到清理沉砂的效果,另外,设置的喷嘴容易陷入罐体底部的沉砂中,使得叶轮转动所需扭矩增大,造成能源浪费,而设置的喷缝38是在第一进液轴管31上直接开设条孔,因此不需要增加扭矩便能轻易实现该钻井液缝喷叶轮的运转;通过设置喷缝38的出液方向与第一进液轴管31在喷缝38位置处的切线方向形成锐角,这样便保证了喷缝38在出液时在水平面上有一定的倾角,当该装置进行搅拌工作时,先启动喷缝38喷液,喷缝38喷液形成一定的反作用力,辅助驱动第一进液轴管31往相反方向转动,提升了该装置搅拌功能的启动效率,此时喷缝38喷出液体的方向和叶轮叶片32倾斜的方向相同,叶轮叶片32的下面为工作面,叶轮叶片32将液体压向罐底,使钻井液形成漩涡状液体流,减小了叶轮的转矩;当该装置实施混合功能时,此时喷缝38喷出液体的方向和叶轮叶片32倾斜的方向相同,叶轮叶片32的下面为工作面,叶轮叶片32将液体压向罐底,使钻井液形成漩涡状液体流,减小了叶轮的转矩;当该装置实施清洁功能时,此时罐中无钻井液,开启混合传动装置4阀门并启动第一进液轴管31,此时喷缝38喷出的液体形成一个覆盖面,增大了对罐底的清洁面积,大大提升了清洁效果,此时叶轮旋转方向与喷缝38喷出液体方向一致,进一步加强了喷缝38喷出液体的冲击力,这样使得罐底的沉积得到最大限度的清洁,本专利中的喷缝38叶 轮的喷缝38喷出的液体和叶轮的倾斜方向相同,其工况为,搅拌功能时液体呈现漩涡状液体流,混合时液体呈现漩涡状液体流,清洁时液体呈现喷泉状液体流,这样的设计可以减小叶轮的转矩,从而可以减小电机的功率节省能源;通过设置内层孔的上边缘高于外层孔的上边缘,内层孔的下边缘高于外层孔的下边缘,这样便使得喷缝38处形成了一个向下的倾斜面,这样便能够增强喷缝38向下的冲击力,更进一步提升了清理沉砂的效率。

中空叶片35和副叶片36均呈“J”型或者“S”型设置。
实施例5
一种钻井液混合清洁搅拌装置的控制方法,包括搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法,其中:
一种钻井液混合清洁搅拌装置的控制方法,包括搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法。
搅拌功能的控制方法、混合功能的控制方法和清洁功能的控制方法为全自动的控制方法,其中:
搅拌功能的控制方法具体包括以下步骤:操作者按下搅拌按钮,系统开启混合传动装置阀门,待阀门完全开启后系统自动启动电机,此时电机带动叶轮做逆时针旋转,叶片下叶面为工作面,液体呈现旋涡状液体流,待叶轮旋转稳定后,系统关闭混合传送装置的阀门,此时处于搅拌状态,搅拌完成,操作者按下停止按钮,系统关闭电机,完成搅拌功能。
搅拌功能:在需要对钻井液进行搅拌时,为了减小叶轮的轴向受力设计叶轮的旋转后的液流方向为漩涡状液体流,由于喷缝喷出液体的方向与叶轮的倾斜方向相同,液体喷出后的反作用力使叶轮叶片的下面为工作面,而电机旋转时带动叶轮旋转时,也是设计成叶轮叶片的下面为工作面,喷缝喷出的液体不仅冲散了叶轮下部周围钻井液使其呈现悬浮状态,而且喷缝喷出的液体给叶轮一个旋转的力从而减小了电机启动的转矩,辅助电机的旋转。搅拌功能的运行程序为:首先混合传动装置阀门打开,钻井液进入叶轮轴管并从轴管的喷缝喷出,由于喷缝喷出的方向和叶轮叶片倾斜的方向相同,液体喷出的钻井液使叶轮下端的钻井液被冲散,并使其处于悬浮状态,在喷出液体的反作用力下使叶轮叶片下面为工作面,然后启动电机带动叶轮旋转,电机带动叶轮旋转把液体压向罐底,使钻井液形成漩涡状液体流,而喷缝喷出的钻井液与漩涡状液体流的钻井液方向相同,加速了钻井液的流动并给叶轮一个转动力辅助叶轮旋转,待叶轮旋转平稳后,关闭混合传动装置阀门,该装置一直处于此运行状态,直到人工关闭搅拌功能为止。
混合功能的控制方法具体包括以下步骤:操作者按下混合按钮,系统开启混合传动装置阀门,待阀门完全开启后系统自动启动电机,此时电机带动叶轮 做逆时针旋转,叶片下叶片为工作面,液体呈现旋涡状液体流,此时处于混合状态,混合完毕,操作者按下停止按钮,系统关闭混合传动装置阀门以及电机,完成混合功能。
混合功能:混合功能是辅助加重系统对钻井液进行加重(稀释)作业,为了减小叶轮的轴向力以及叶轮的转矩选择液体流为漩涡状液体流。当在加重时,将混合传动装置的阀门和加重系统的输出管线直接连通,加重作业时先打开混合传动装置阀门,加重系统输出管线运输来的钻井液进入叶轮轴管并从轴管的喷缝喷出,由于喷缝喷出的方向和叶轮叶片倾斜的方向相同,在喷出液体的反作用力下使叶轮叶片下面为工作面,然后启动电机带动叶轮旋转,电机带动叶轮旋转把液体压向罐底,使罐内液体形成漩涡状液体流,而喷缝喷出的液体与漩涡状液体流的钻井液方向相同,加速了罐内液体的流动并给叶轮一个转动力辅助叶轮旋转,加速了液体的流动,加快了液体的混合,直到加重作业完成,当混合完成后,只需要关闭混合传动装置的阀门就可以了,此时叶轮仍然处于搅拌状态,直到停止运行关闭电机。
清洁功能的控制方法具体包括以下步骤:操作者按下清洁按钮,系统自动开启电机,电机带动叶轮顺时针旋转,待叶轮旋转平稳后,系统开启混合传动装置阀门,此时处于清洁功能状态,清洁完毕,操作者按下停止按钮,系统关闭混合传动装置阀门以及电机,完成清洁功能。
清洁功能:清洁功能为最后清洁罐体用。此时罐体内的钻井液已经基本放完,罐内只剩下罐底的沉砂,叶轮基本处于悬浮状态。为了加大液体的喷射冲击效果,叶轮的旋转与喷缝喷出液体的方向相同,也就是说如果此时罐内有液体的话,叶轮叶片的上面为工作面,叶轮旋转时使液体呈现喷泉状体液流。当需要对罐底进行清洁时,首先把清水管线和泥浆枪管线或加重输出管线连接, 启动电机,电机带动叶轮旋转,待叶轮旋转平稳后,混合传动装置阀门开启清水进入,清水不仅可以用来冲击罐内的沉砂,清水在泥浆枪管线或加重输出管线内流动时也对泥浆枪管线内的沉砂和加重输出管线内的沉砂进行了清洁,清水从喷缝内喷出,由于液体喷出的方向和叶轮旋转的方向相同,叶轮旋转加强了喷缝喷出液柱的冲击效果,从而更有效的冲击罐底的沉砂,沉砂被不停地冲击,并被水流带走,从而有效的清洁了罐底的沉砂。
以上搅拌功能、混合功能、清洁功能之间可以相互切换。如在搅拌功能状态下开启混合功能,操作者只需要按下混合按钮即可,系统会按照相应程序切换到混合功能。
